GSM alarms

GSM alarms

GSM alarms used in security and monitoring are gaining increasing popularity. Their use is quite broad, ranging from ordinary urban properties and private homes to large facilities and industrial enterprises. The origins of GSM alarm technology go back to radio pagers, which allowed owners to monitor their vehicles from a distance of 200-300 meters.

A GSM alarm system is quite simple. It consists of sensors and a GSM module connected to the control panel. If a sensor is activated, indicating an unauthorized intrusion, the GSM module sends an SMS to the owner's mobile phone. More advanced models feature voice calls to the mobile phone, as well as the ability to activate and deactivate the entire system from there.

A GSM alarm is installed on a property to ensure its security. When choosing an alarm system, consider the following recommendations:

  • A GSM alarm is a single unit consisting of a GSM module and a control panel. The alarm system should also be purchased as a single unit, as testing of a specific module occurs in conjunction with a specific control panel. If you use a panel and module from different manufacturers, they may not provide the required level of control or may not function at all.
  • GSM modules and panels must be factory-made; a home-assembled device will not function properly.
  • The relevant product must have documents confirming its certification.

Considering the overall advantages of GSM alarms, some should be noted:

  • GSM networks offer extensive coverage, greater than any radio station.
  • Mobile phone services are inexpensive.
  • Installing a GSM system is quite practical and does not require much time.
  • Mobile operators offer additional services (SMS messaging) specifically for GSM alarms.
  • GSM alarms are relatively inexpensive.

The power supply options for GSM alarms are also important. Power can be supplied solely from a 220V network or a 12V car battery. Another option is to have a backup power source in addition to the main power supply. When using a GSM alarm on moving objects, additional features include connecting a GPS navigator, allowing for additional monitoring and tracking of the object's route.

For increased reliability, GSM alarms can alert the owner of poor coverage. If such a problem is anticipated, it would be advisable to configure the GSM module to work with multiple SIM cards.

When purchasing security equipment, it is important to consider integrating it with modern communications technology. GSM coverage is the most accessible means of transmitting information over long distances today, so a GSM alarm will provide you with a high level of control and security.
